Hi all,
Sorry if this has already been mentioned here -- I couldn't find any prior coverage. Beretta is providing a free recoil spring + guiding rod replacement for Px4 Compact that are affected by the feeding/extraction problems. Below is the link:

I have been dismayed at sporadic FTFs with most 115gr in my 9mm Compact, and my gunsmith suggested to replace the spring. Running a quick Google search turned up that link above.
